J. w. BRUNETTE SYRINGE Filed March 2, 1929 Inventor J 5 110185? Wad/5% B y "Amrhey Patented Mar. 25, 1930 JOSEPH W, BRTTNETTE, OF FORDSON, MICHIGAN SYRINGE v Application filed March 2,

The present invention relates to improvements in the class of surgical instruments, and more particularly the same has reference to a novel syringe of the douche type.

The salient object of this invention is to provide a syringe having means whereby the injected douche fluid may be readily drainedfrom the vagina.

Another object of importance is to provide a syringe of this character wherein the parts may be'easily disassembled to be cleaned,

' replaced, or repaired.

These and other objects of the invention become more apparent to the reader after considering the invention as' described and claimed hereinafter.

In the drawing Figure 1 represents a longitudinal sectional view through the improved syringe.

Fig. 2 is an end elevation of the novel syringe.

Fig. 3 is a longitudinal sectional view through a nozzle element of resilient material adapted for use with the present invention. v

Fig. 4 is an end elevation of the nozzle element shown in Fig. 3. A i

Referring to the drawings wherein like numerals designate like parts, a body 1 preferably concaved at its inner side 2 is provided with an opening 3 extending throughits enlarged intermediate portion, which takes the form of a protuberance 4, projecting from the inner face of the body.

The protuberance 4 is provided with a plurality of radially disposed and outwardly converging openings 5. The body 1 has a recess 6 adjacent one end thereof, and at the outer side in which the threaded portion of a nipple 7 is'engaged.

A duct 8 communicates the recess 6 with the opening 3. A nozzle member 9 is pro vided with a reduced extension 10 at its open end for engagement within the free end por F tion of the protuberance 4., while. a nipple element 11 is provided with a reduced extension 12 at one end for insertion within the opening 3. a

Extending longitudinally from the reduced portion 12 is a tube 13, which is adapt 1929. Serial Nb. 343,974.

ed for threaded engagement within the open end of the nozzle 9. The nozzle 9 isprovided with perforations 14 at its closed end portion.

In Fig. 3, a'modified form of nozzle is shown. This nozzle is preferably constructed of resilient material such as rubber. This modified nozzle is denoted by the numeral 15 and is perforated at its closed end 16, in the manner shown. The open end of the nozzle 15 is adapted to receive an internally threaded bushing 17 from which extends a reduce,

ment 18 for engagement with the open end of the protuberance 4, as in the manner of the nozzle 9.

A suitable fluid supply tube is engaged over the nozzle 11 and a drain tube can be engaged over the permitted to flow 9, will after sufliciently ballooning the vagina by obstructing the drain tube, can be allowed to return through the opening 5 to the chamher 3, and then through the duct 8 and nipple 7 to the drain tube.

Obviously, numerous specific changes may be made in the construction of this device, without departing from the spirit and scope thereof, as claimed hereinafter.

Having thus described my invention, what I claim as new is A syringe comprising a substantially flat body having an tion in which a enlarged intermediate I pordrain chamber is provided,

a nipple for insertion within the chamber at one side of the body,

a hollow perforated nozzle member, said nozzle member being internally threaded at one end, a reduced tubular extension on said nipple, said extension being adapted to have its free end portion threadedly engaged within the threaded end portion-of the nozzle,

hung at one s1 catlng with the $21.1

a fluid inlet, said inlet d chamber, and an outlet communicating with the chamber and opening through the opposite side of the body.

In testimony whereof TOSEPH w. BRUNETTE.

I afiix my signature.
